This mixing valve 3 is connected to a mixing valve 31 for mixing water and hot water.
The mixing channel 60 from 1 is connected to the peripheral device 20.
Here, when the supplied hot water is high-temperature water of 70 ° C. or higher, particularly in the case of hot water supplied from an electric water heater using midnight power, the temperature may be 90 ° C. or higher. Is supplied to the peripheral device 20, there is a risk that the user may be burned by the high-temperature water itself or the heated peripheral device 20, and the peripheral device 20 itself may be significantly deteriorated or damaged. . Furthermore, in particular the peripheral device 20
Is a dishwasher, the supplied hot water has a high temperature, which may have an adverse effect that the dishes become dirty and hard to remove. Therefore, in the conventional faucet facility 110, high-temperature water and water are mixed in advance in the mixing valve 31, and the mixed water whose temperature has been reduced to an appropriate temperature is supplied to the peripheral device 20.

[0003]

The conventional faucet equipment 1
In 10, the hot water from the hot water supply channel 50 flows directly into the hot and cold water mixing faucet 10, is appropriately mixed with the water from the water supply channel 40 by the valve device 11 in the hot and cold water mixing faucet 10, and is discharged from the water outlet. . However, when the hot water from the hot water supply path 50 is high-temperature water, such high-temperature water is directly supplied to the hot-water mixing faucet 1.
0 will be supplied. Therefore, there is a problem that the user may be burned due to the hot water / water mixture faucet 10 or high-temperature water spouting, and a problem that the water / water mixture faucet 10 may be significantly deteriorated or damaged. I was

The present invention solves the above-mentioned problems of the conventional faucet facilities.
